Lowndes was also a horror enthusiast—as a young fan, he received two letters of encouragement from H. P. Lovecraft in 1937.[1] He wrote a number of dark fantasy stories such as "The Abyss" (1941) and "The Leapers" (1942), inspired by Lovecraft. In 1963, Lowndes initiated the Magazine of Horror (1963–1971) for Health Knowledge Inc., which mixed reprints with new stories.[2] The magazine was popular and spawned several companion magazines: Startling Mystery Stories, Famous Science Fiction (both 1966) Weird Terror Tales (1969) and Bizarre Fantasy Fiction (1970). Lowndes also edited two non-fantastic-fiction magazines for the company, Thrilling Western Magazine (1967) and World Wide Adventure (1967), along with the speculative nonfiction titles they published.[2] However, the collapse of Health Knowledge in 1971 ended these magazines.[3]Startling Mystery Stories was notable for carrying the first stories of Stephen King and F. Paul Wilson.[4] Lowndes subsequently went on to work on the Gernsback Publications' non-fiction magazine, Sexology.[2]
